Description

Technical Field

[0001] The present invention relates to the technical field of intelligent wearable devices, and in particular to intelligent blind-aiding glasses. Background Art

[0002] Blind people, also known as visually impaired people, refer to people whose vision is severely impaired or completely lost due to diseases of the optic nerve or eyes or accidental injuries. They are divided into two categories: total blindness and partial blindness. Total blindness refers to atrophy or calcification of the eyeball, which loses its response to light; partial blindness (or amblyopia) refers to vision less than 60% of normal. Due to visual impairment and limited range of activities, blind people face many challenges in their daily life and social participation. However, through the development of modern science and technology, the quality of life and independence of the blind have been significantly improved. Smart glasses for the blind are one of the important inventions. Smart glasses for the blind are a high-tech auxiliary device that combines advanced technologies such as artificial intelligence, computer vision and the Internet of Things to provide comprehensive visual assistance services for the blind.

[0003] In the prior art, a Chinese patent document with publication number CN218552560U proposes a pair of smart glasses for assisting the blind, including a frame, temples, a recognition module and an operation module. The temples are provided with a voice module, and the voice module is used to broadcast the signal transmitted by the recognition module by voice. The recognition module is preset with multiple auxiliary modes; the operation module includes a control, one-key help, clear cache and mode switching unit. Although the control, one-key help, and clear cache units are used to perform relevant processing on the recognition module, the performance requirements of the recognition module are reduced and lowered, and the service module is replaced by the mode switching unit. The data processing of the device reduces the amount of data transmission between the recognition module and the server, and improves the processing efficiency and real-time transmission of the recognition module and the server. However, this technology is consistent with the traditional method in that when the blind-aiding glasses are not in use, especially when they are placed on the bedside table at night, due to the limited vision of the user, when trying to take other items on the bedside table, they may accidentally touch the glasses, causing them to fall accidentally. Since the front end of the blind-aiding glasses in the prior art, such as key components such as cameras or laser radars, lacks the necessary protection design, such a fall often causes impact on these precision components, thereby causing damage. Once these core functional components are damaged, the blind-aiding glasses will lose their due auxiliary functions, causing trouble and distress to users.

[0004] Furthermore, we disclose a pair of smart blind-aiding glasses to meet the practical needs of solving the problem that key components such as cameras or lidars on the blind-aiding glasses in the prior art are easily damaged by falling. Summary of the invention

[0031] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0032] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs. The "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0033] like Figures 1 to 10 As shown, a kind of intelligent blind-aiding glasses comprises a frame 1 with a CPU controller therein, two ends of one side of the frame 1 are rotatably connected with temples 2, the inner middle parts of the two temples 2 are inlaid with vibrators 3, a laser radar 7 is arranged in the middle of the front end of the frame 1, an opening and closing component is arranged in the middle of the front end surface of the frame 1, the opening and closing component is arranged at the front end of the laser radar 7, the opening and closing component is used to protect the laser radar 7 from damage when falling, the opening and closing component is driven by the rotation of the temple 2, a damping component is arranged at the connection between the temple 2 and the frame 1, the damping component is used to limit the rotation position of the temple 2 and thus maintain the opening and closing state of the opening and closing component;

[0034] When the glasses are being worn, the temple 2 naturally fits against the user's ear. At this time, the opening and closing assembly remains open to ensure that the laser radar 7 works smoothly. When the glasses are not in use, the user will turn the temple 2 to fit the inside of the glasses. This action will trigger the opening and closing assembly to close quickly. After that, if the glasses accidentally fall, since the opening and closing assembly is in a closed state at this time, it is like installing an instant protective cover for the laser radar 7, which effectively prevents direct impact during the fall and reduces damage to the internal laser radar 7, ensuring that it can work normally. In addition, in order to ensure that the opening and closing assembly can be stably opened and closed when needed, a damping assembly is also built into the connection between the temple 2 and the frame 1. This assembly not only provides the necessary friction, allowing the user to fine-tune the angle of the temple 2 according to the wearing comfort, but more importantly, it can lock the position of the temple 2 after the opening and closing assembly is closed to maintain the protection state of the laser radar 7 until the user wears the glasses again and adjusts the temple 2 to its original position, the opening and closing assembly will be reopened, increasing the protection effect on the laser radar 7.

[0035] Further, such as Figures 1 to 3 , Figures 7 to 10As shown, the opening and closing assembly includes a fixed plate 20, both ends of the fixed plate 20 are fixedly connected with brackets 19, the two brackets 19 are fixedly connected to the frame 1 on one side close to the frame 1, a turntable 22 is provided on the side of the fixed plate 20 close to the frame 1, a plurality of waist-shaped grooves 23 are evenly spaced apart in the middle of the turntable 22, a plurality of triangular pieces 21 are provided between the fixed plate 20 and the turntable 22, the number of the triangular pieces 21 is the same as the waist-shaped grooves 23, a limiting column 25 is fixedly connected to one side of the triangular piece 21, and an end of the limiting column 25 close to the turntable 22 is slidably connected to the inside of the waist-shaped groove 23, a plurality of triangular pieces 21 are fixedly connected to the outer side of the end surface of one side close to the fixed plate 20, and a plurality of triangular pieces 21 are evenly spaced apart on the end surface of one side close to the triangular piece 21 A guide groove 27, a limit strip 26 is slidably connected inside the guide groove 27, a limit groove 4 is provided in the middle of the front end surface of the frame 1, a plurality of sliders 24 are fixedly connected to the upper end of the end surface of the turntable 22 close to the frame 1, the sliders 24 are arc-shaped and slidably engaged in the limit groove 4, a plurality of tooth blocks 10 are fixedly connected to the lower end of the end surface of the turntable 22 close to the frame 1 by the axis array of the turntable 22, an open groove 8 is provided at the lower middle end of the front end surface of the frame 1, a rack 6 is slidably connected inside the open groove 8, the rack 6 is meshed with the tooth block 10 on the turntable 22, two return springs 5 ​​are fixedly connected to one side of the inner wall of the open groove 8, one end of the two return springs 5 ​​are fixedly connected to the rack 6, and a wire rope 9 is fixedly connected to the middle of the end surface of the rack 6 close to the return spring 5;

[0036] When the glasses are not in use, the user will rotate the temples 2 to fit the inside of the glasses. This action will pull the wire rope 9, one end of which is connected to the rack 6. When the wire rope 9 is pulled, the rack 6 will slide along the inner wall of the open groove 8, and the rack 6 will be meshed with the tooth block 10 on the turntable 22. Therefore, the movement of the rack 6 will drive the turntable 22 to rotate. The multiple sliders 24 on the turntable 22 are slidably engaged in the limiting grooves 4 of the frame 1, limiting the movement of the turntable 22 in a direction perpendicular to the plane of the frame 1, ensuring that the turntable 22 can only rotate around its axis. A plurality of waist grooves 23 are evenly spaced apart on the outside of the middle part of the turntable 22, and the triangular piece 21 is slidably connected in these waist grooves 23 through the limiting columns 25. As the turntable 22 rotates, the triangular piece 21 will move along the waist groove 23 and drive it close to one side of the fixed plate 20. The limit strip 26 on the outer side of the end face slides in the guide groove 27, and the interaction between the triangular piece 21 and the turntable 22 and the fixed plate 20 causes the opening and closing assembly to close quickly, providing an instant protective cover for the laser radar 7. Once the glasses accidentally fall, since the opening and closing assembly is in a closed state at this time, it can effectively prevent the direct impact during the falling process from damaging the internal laser radar 7, greatly reducing the risk of damage to the internal laser radar 7 and ensuring that it can continue to work normally. When the user wears the glasses again and adjusts the temples 2 to their original position, the wire rope 9 becomes loose, and under the action of the reset spring 5, the rack 6 will slide in the opposite direction along the inner wall of the opening groove 8, driving the turntable 22 to rotate in the opposite direction. The rotation of the turntable 22 will drive the triangular piece 21 and the limit strip 26 to move in the opposite direction along the waist groove 23 and the guide groove 27, thereby reopening the opening and closing assembly.

[0037] Further, such as Figures 1 to 6 As shown, the damping assembly includes a rotating seat 11 fixedly connected to the side of the temple 2 close to the frame 1, a rotating shaft 14 is fixedly connected to the middle of the rotating seat 11, a spiral groove 12 is provided in the middle of the outer wall of the rotating shaft 14 on one side, one end of the wire rope 9 away from the rack 6 is wound around the spiral groove 12 and the tail end is fixedly connected to the rotating shaft 14, the upper and lower ends of both sides of the frame 1 are threadedly connected with threaded columns 15, one side of the outer wall of the threaded column 15 is threadedly connected with two locking nuts 13, one end of the two threaded columns 15 close to the rotating shaft 14 is provided with a mounting groove 17, both ends of the rotating shaft 14 are respectively inserted into the mounting groove 17, an inner wall of the mounting groove 17 is fixedly connected to the middle of the end surface of one side away from the rotating shaft 14, an extrusion spring seat 16 is fixedly connected to one end of the extrusion spring seat 16, an end of the extrusion plate 18 is fixedly connected, an end surface of the extrusion plate 18 away from the extrusion spring seat 16 is in contact with the rotating shaft 14, and the extrusion plate 18 is made of friction material;

[0038] When the temple 2 rotates relative to the frame 1, the rotating seat 11 rotates accordingly, and the rotating shaft 14 fixedly connected in the middle of the rotating seat 11 is maintained in the mounting groove 17 on the frame 1, and a spiral groove 12 is provided in the middle of the outer wall of the rotating shaft 14, one end of the wire rope 9 is wound around the spiral groove 12 and fixedly connected to the rotating shaft 14, and the other end is connected to the rack 6, so that when the temple 2 rotates, the rack 6 is pulled by the wire rope 9, thereby driving the opening and closing of the opening and closing assembly. The key is that an extrusion spring seat 16 is fixedly connected in the middle of the end surface of the inner wall of the mounting groove 17 away from the rotating shaft 14, and one end of the extrusion spring seat 16 is fixedly connected to an extrusion plate 18 made of a friction material, and the extrusion plate 18 contacts the rotating shaft 14 and is squeezed The elastic force of the spring seat 16 always maintains the friction resistance to the rotating shaft 14. The selection of the friction resistance material and the setting of the elastic force of the extrusion spring seat 16 make the rotating shaft 14 be subjected to a certain damping force during the rotation process, thereby realizing the fine-tuning function of the angle of the temple 2 and being able to lock the position of the temple 2 after the opening and closing assembly is closed. In addition, the upper and lower ends of both sides of the frame 1 are threadedly connected with threaded columns 15, and one side of the outer wall of the threaded column 15 is threadedly connected with two locking nuts 13. By adjusting the position of the locking nut 13, the friction resistance of the extrusion plate 18 to the rotating shaft 14 can be further adjusted, thereby realizing the adjustment of the damping force. This design not only increases the comfort and convenience of use, but also improves the stability and reliability of the opening and closing assembly.
